Abstract (en)
[origin: GB2588411A] A drive system for a side mounted cycle wheel 4, comprising a wheel hub 18 for mounting the side mounted cycle wheel 4; a motor drive 9 for driving the side mounted cycle wheel, the motor drive comprising an electric motor 10,11 and a planetary gear 26 reduction assembly positioned at least partially within the wheel hub 18; and, a rotary wheel hub bearing 20 rotatably coupling the wheel hub 18 to the motor drive 9, wherein the rotary wheel hub bearing 20 is positioned laterally between the electric motor 10,11 and the planetary gears 26. The bearing 20 may be of smaller diameter than either the motor stator 10 or the wheel hub 18. The drive may be used in a cycle or other electric vehicle.
